Space is more accessible than ever thanks to the proliferation of small satellites and more affordable launch prices, which opened the door to bespoke applications like global pollution monitoring, crop observations, and new ways of collecting weather and climate data.

Now you can add wildfire detection to the list. Satellites have observed wildfires from space for decades, but a new initiative partially funded by Google's philanthropic arm aims to deploy more than 50 small satellites in low-Earth orbit to pinpoint flare-ups as small as a classroom anywhere in the world.

The FireSat constellation, managed by a nonprofit called Earth Fire Alliance (EFA), will be the first satellite fleet dedicated to detecting and tracking wildfires. Google announced a fresh investment of $13 million in the FireSat constellation Monday, building on the tech giant's previous contributions to support the development of custom infrared sensors for the FireSat satellites.

NASA astronauts Butch Wilmore and Suni Williams are no strangers to time away from their families. Both are retired captains in the US Navy, served in war zones, and are veterans of previous six-month stays on the International Space Station.

When they launched to the space station on Boeing's Starliner spacecraft on June 5, the astronauts expected to be home in a few weeks, or perhaps a month, at most. Their minimum mission duration was eight days, but NASA was always likely to approve a short extension. Wilmore and Williams were the first astronauts to soar into orbit on Boeing's Starliner spacecraft, a milestone achieved some seven years later than originally envisioned by Boeing and NASA.

However, the test flight fell short of all of its objectives. Wilmore and Williams are now a little more than three months into what has become an eight-month mission on the station. The Starliner spacecraft was beset by problems, culminating in a decision last month by NASA officials to send the capsule back to Earth without the two astronauts. Rather than coming home on Starliner, Wilmore and Williams will return to Earth in February on a SpaceX Dragon spacecraft.

The Federal Aviation Administration has signaled to SpaceX that it won't approve a launch license for the next test flight of the Starship rocket until at least late November, the company said in a statement on Tuesday.

This is more than two months later than the mid-September timeframe the FAA previously targeted for determining whether to approve a launch license for the next Starship flight. SpaceX says the Super Heavy booster and Starship upper stage for the next launchβ€”the fifth full-scale test flight of the Starship programβ€”have been ready to launch since the first week of August.

"The flight test will include our most ambitious objective yet: attempt to return the Super Heavy booster to the launch site and catch it in mid-air," SpaceX said in a statement.

Boeing's Starliner spacecraft sailed to a smooth landing in the New Mexico desert Friday night, an auspicious end to an otherwise disappointing three-month test flight that left the capsule's two-person crew stuck in orbit until next year.

Cushioned by airbags, the Boeing crew capsule descended under three parachutes toward an on-target landing at 10:01 pm local time Friday (12:01 am EDT Saturday) at White Sands Space Harbor, New Mexico. From the outside, the landing appeared just as it would have if the spacecraft brought home NASA astronauts Butch Wilmore and Suni Williams, who became the first people to launch on a Starliner capsule on June 5.

But Starliner's cockpit was empty as it flew back to Earth Friday night. Last month, NASA managers decided to keep Wilmore and Williams on the International Space Station (ISS) until next year after agency officials determined it was too risky for the astronauts to return to the ground on Boeing's spaceship. Instead of coming home on Starliner, Wilmore and Williams will fly back to Earth on a SpaceX Dragon spacecraft in February. NASA has incorporated the Starliner duo into the space station's long-term crew.

Boeing's Starliner spacecraft will gently back away from the International Space Station Friday evening, then fire its balky thrusters to rapidly depart the vicinity of the orbiting lab and its nine-person crew.

NASA asked Boeing to adjust Starliner's departure sequence to get away from the space station faster and reduce the workload on the thrusters to reduce the risk of overheating, which caused some of the control jets to drop offline as the spacecraft approached the outpost for docking in June.

The action begins at 6:04 pm EDT (22:04 UTC) on Friday, when hooks in the docking mechanism connecting Starliner with the International Space Station (ISS) will open, and springs will nudge the spacecraft away its mooring on the forward end of the massive research complex.

NASA is ready for Boeing's Starliner spacecraft, stricken with thruster problems and helium leaks, to leave the International Space Station as soon as Friday, wrapping up a disappointing test flight that has clouded the long-term future of the Starliner program.

Astronauts Butch Wilmore and Suni Williams, who launched aboard Starliner on June 5, closed the spacecraft's hatch Thursday in preparation for departure Friday. But it wasn't what they envisioned when they left Earth on Starliner three months ago. Instead of closing the hatch from a position in Starliner's cockpit, they latched the front door to the spacecraft from the space station's side of the docking port.

The Starliner spacecraft is set to undock from the International Space Station at 6:04 pm EDT (22:04 UTC) Friday. If all goes according to plan, Starliner will ignite its braking rockets at 11:17 pm EDT (03:17 UTC) for a minute-long burn to target a parachute-assisted, airbag-cushioned landing at White Sands Space Harbor, New Mexico, at 12:03 am EDT (04:03 UTC) Saturday.

NASA and Boeing are proceeding with final preparations to undock the Starliner spacecraft from the International Space Station next Friday, September 6, to head for landing at White Sands Space Harbor in southern New Mexico.

Astronauts Butch Wilmore and Suni Williams, who were supposed to return to Earth inside Starliner, will remain behind on the space station after NASA decided last week to conclude the Boeing test flight without its crew on board. NASA officials decided it was too risky to put the astronauts on Starliner after the spacecraft suffered thruster failures during its flight to the space station in early June.

Instead, Wilmore and Williams will come home on a SpaceX Dragon capsule no earlier than February, extending their planned stay on the space station from eight days to eight months. Flying on autopilot, the Starliner spacecraft is scheduled to depart the station at approximately 6:04 pm EDT (22:04 UTC) on September 6. The capsule will fire its engines to drop out of orbit and target a parachute-assisted landing in New Mexico at 12:03 am EDT (04:03 UTC) on September 7, NASA said in a statement Thursday.

Pretty much every day for the last couple of weeks, workers wielding welding guns and torches have climbed onto SpaceX's Starship launch pad in South Texas to make last-minute upgrades ahead of the next test flight of the world's largest rocket.

Livestreams of the launch site provided by LabPadre and NASASpaceflight.com have shown sparks raining down two mechanical arms extending from the side of the Starship launch tower at SpaceX's Starbase launch site on the Gulf Coast east of Brownsville, Texas. We are publishing several views here of the welding activity with the permission of LabPadre, which runs a YouTube page with multiple live views of Starbase.

If SpaceX has its way on the next flight of Starship, these arms will close together to capture the first-stage booster, called Super Heavy, as it descends back to Earth and slows to a hover over the launch pad.

Seven months after its first lunar lander fell short of reaching the Moon, Astrobotic announced Tuesday that the spacecraft was stricken by a valve failure that caused a propellant tank to burst in orbit. The company's next landing attempt, using a much larger spacecraft, will include fixes to prevent a similar failure.

Astrobotic's first Peregrine lander, which the company called Peregrine Mission One, launched on January 8 aboard United Launch Alliance's first Vulcan rocket. But soon after separating from the rocket in space, the lander ran into trouble as it stepped through an activation sequence to begin priming its propulsion system.

A review board determined "the most likely cause of the malfunction was a failure of a single helium pressure control valve called a PCVβ€”pressure control valve 2, within the propulsion system," said John Horack, a space industry veteran and professor of aerospace and mechanical engineering at Ohio State University.

Ten years ago next month, NASA announced that Boeing, one of the agency's most experienced contractors, won the lion's share of government money available to end the agency's sole reliance on Russia to ferry its astronauts to and from low-Earth orbit.

At the time, Boeing won $4.2 billion from NASA to complete the development of the Starliner spacecraft and fly a minimum of two, and potentially up to six, operational crew flights to rotate crews between Earth and the International Space Station (ISS). SpaceX won a $2.6 billion contract for essentially the same scope of work.

A decade later, the Starliner program finds itself at a crossroads after Boeing learned it will not complete the spacecraft's first Crew Flight Test with astronauts onboard. NASA formally decided Saturday that Butch Wilmore and Suni Williams, who launched on the Starliner capsule on June 5, will instead return to Earth in a SpaceX Crew Dragon spacecraft. Put simply, NASA isn't confident enough in Boeing's spacecraft after it suffered multiple thruster failures and helium leaks on the way to the ISS.

Senior NASA leaders, including the agency's administrator, Bill Nelson, will meet Saturday in Houston to decide whether Boeing's Starliner spacecraft is safe enough to ferry astronauts Butch Wilmore and Suni Williams back to Earth from the International Space Station.

The Flight Readiness Review (FRR) is expected to conclude with NASA's most consequential safety decision in nearly a generation. One option is to clear the Starliner spacecraft to undock from the space station in early September with Wilmore and Williams onboard, as their flight plan initially laid out, or to bring the capsule home without its crew.

As of Thursday, the two veteran astronauts have been on the space station for 77 days, nearly 10 times longer than their planned stay of eight days. Wilmore and Williams were the first people to launch and dock at the space station aboard a Starliner spacecraft, but multiple thrusters failed and the capsule leaked helium from its propulsion system as it approached the orbiting complex on June 6.

The first stage of Rocket Factory Augsburg's first orbital launcher was destroyed in a fireball during a test-firing Monday evening at a spaceport in Scotland, the company said.

The German launch startup aimed to send its first rocket into space later this year and appeared to be running ahead of several competitors in Europe's commercial launch industry that are also developing rockets to deploy small satellites in orbit.

Within the last few months, Rocket Factory Augsburg (RFA) delivered all three stages of its first rocket, named RFA One, to its launch site at SaxaVord Spaceport, located on Unst, one of the Shetland Islands and the northernmost inhabited island in the United Kingdom. The company is based in Augsburg, Germany.

Two NASA spacecraft built by Rocket Lab are on the road from California to Florida this weekend to begin preparations for launch on Blue Origin's first New Glenn rocket.

These two science probes must launch between late September and mid-October to take advantage of a planetary alignment between Earth and Mars that only happens once every 26 months. NASA tapped Blue Origin, Jeff Bezos' space company, to launch the Escape and Plasma Acceleration and Dynamics Explorers (ESCAPADE) mission with a $20 million contract.

Last November, the space agency confirmed the $79 million ESCAPADE mission will launch on the inaugural flight of Blue Origin's New Glenn rocket. With this piece of information, the opaque schedule for Blue Origin's long-delayed first New Glenn mission suddenly became more clear.

There are more than 2,000 mostly intact dead rockets circling the Earth, but until this year, no one ever launched a satellite to go see what one looked like after many years of tumbling around the planet.

In February, a Japanese company named Astroscale sent a small satellite into low-Earth orbit on top of a Rocket Lab launcher. A couple of months later, Astroscale's ADRAS-J (Active Debris Removal by Astroscale-Japan) spacecraft completed its pursuit of a Japanese rocket stuck in orbit for more than 15 years.

ADRAS-J photographed the upper stage of an H-IIA rocket from a range of several hundred meters and then backed away. This was the first publicly released image of space debris captured from another spacecraft using rendezvous and proximity operations.

The astronauts who rode Boeing's Starliner spacecraft to the International Space Station last month still don't know when they will return to Earth.

Astronauts Butch Wilmore and Suni Williams have been in space for 51 days, six weeks longer than originally planned, as engineers on the groundwork through problems with Starliner's propulsion system.

The problems are twofold. The spacecraft's reaction control thrusters overheated, and some of them shut off as Starliner approached the space station June 6. A separate, although perhaps related, problem involves helium leaks in the craft's propulsion system.

Welcome to Edition 7.03 of the Rocket Report! One week ago, SpaceX suffered a rare failure of its workhorse Falcon 9 rocket. In fact, it was the first time the latest version of the Falcon 9, known as the Block 5, has ever failed on its prime mission after nearly 300 launches. The world's launch pads have been silent since the grounding of the Falcon 9 fleet after last week's failure. This isn't surprising, but it's noteworthy. After all, the Falcon 9 has flown more this year than all of the world's other rockets combined and is fundamental to much of what the world does in space.

Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Astra finally goes private, again. A long-simmering deal for Astra's founders to take the company private has been finalized, the company announced Thursday, capping the rocket launch company’s descent from blank-check darling to delisting in three years, Bloomberg reports. The launch company's valuation peaked at $3.9 billion in 2021, the year it went public, and was worth about $12.2 million at the end of March, according to data compiled by Bloomberg. Astra's chief executive officer, Chris Kemp, and chief technology officer, Adam London, founded the company in 2016 with the goal of essentially commoditizing launch services for small satellites. But Astra's rockets failed to deliver and fell short of orbit five times in seven tries.

NASA has spent $450 million designing and building a first-of-its-kind robot to drive into eternally dark craters at the Moon's south pole, but the agency announced Wednesday it will cancel the rover due to delays and cost overruns.

"NASA intends to discontinue the VIPER mission," said Nicky Fox, head of the agency's science mission directorate. "Decisions like this are never easy, and we haven’t made this one, in any way, lightly. In this case, the projected remaining expenses for VIPER would have resulted in either having to cancel or disrupt many other missions in our Commercial Lunar Payload Services (CLPS) line."

NASA has terminated science missions after development delays and cost overruns before, but it's rare to cancel a mission with a spacecraft that is already built.

It's unclear yet how long SpaceX's workhorse Falcon 9 rocket will remain grounded as engineers investigate a rare launch failure last week, but the next test flight of the company's next-generation Starship vehicle appears to be on track for liftoff next month.

On Monday, SpaceX test-fired the 33 Raptor engines on the Starship rocket's Super Heavy booster at the company's Starbase facility in South Texas. The methane-fueled engines fired for about eight seconds, long enough for SpaceX engineers to verify all systems functioned normally. At full power, the 33 engines generated nearly 17 million pounds of thrust, twice the power output of NASA's iconic Saturn V Moon rocket.

SpaceX confirmed the static fire test reached its full duration, and teams drained methane and liquid oxygen from the rocket, known as Booster 12 in the company's inventory of ships and boosters. The upper stage for the next Starship test flight, known as Ship 30, completed the static fire of its six Raptor engines in May.

A SpaceX Falcon 9 rocket suffered an upper stage engine failure and deployed a batch of Starlink Internet satellites into a perilously low orbit after launch from California Thursday night, the first blemish on the workhorse launcher's record in more than 300 missions since 2016.

Elon Musk, SpaceX's founder and CEO, posted on X that the rocket's upper stage engine failed when it attempted to reignite nearly an hour after the Falcon 9 lifted off from Vandenberg Space Force Base, California, at 7:35 pm PDT (02:35 UTC).

Frosty evidence

After departing Vandenberg to begin SpaceX's Starlink 9-3 mission, the rocket's reusable first stage booster propelled the Starlink satellites into the upper atmosphere, then returned to Earth for an on-target landing on a recovery ship parked in the Pacific Ocean. A single Merlin Vacuum engine on the rocket's second stage fired for about six minutes to reach a preliminary orbit.
