NASA Moves Away from an ISS Cargo Contractor

Back in 2016 NASA was looking for more commercial cargo haulers for its International Space Station (ISS), and Sierra Space’s reusable Dream Chaser spaceplane was one of those options. NASA contracted for multiple resupply missions to the ISS. However, all of that is now over.

NASA has announced that the contract has been modified so that Sierra Space is only to provide a “free flight demonstration” in 2026. What that means is that NASA will give the company a chance to prove its technology, but it will stop financing these efforts. And NASA will not commit to any future resupply missions, but may choose to do so at a later point.

It sounds like quite a gut-punch to another commercial option for the ISS at the same time that Boeing’s Starliner is still limping along. That leaves SpaceX and Northrop Grumman as the only players on the field as the station heads towards it decommissioning in 2030.

Sierra Space can certainly pursue other commercial space opportunities, which is expected to include commercial space stations at some point in the future. Even so, it appears NASA has lost confidence in the company’s ability to deliver on earlier promises related to the ISS.

In a recent press release, the company has put the most positive spin it can on this new arrangement:

Sierra Space is prioritizing first-flight readiness with Dream Chaser, targeting a launch in late 2026 to align with expected launch vehicle availability. Sierra Space and NASA worked together to reach this mutually beneficial agreement that provides greater mission flexibility for Dream Chaser’s first flight. This flight aims to demonstrate critical capabilities for NASA’s ISS resupply and future Commercial LEO Destinations (CLD) missions and position Dream Chaser as a national asset available for future national security and defense demonstrations.

Sierra Space has many other ongoing projects under a variety of government and private sector contracts, including NASA. For instance, it signed a contract with NASA earlier this year to study the use of the company’s expandable space station technology on the Moon.

So the company will be staying busy even after this latest setback. That said, getting the Dream Chaser into orbit on schedule has to remain a key priority for a company that want’s to be a big player in the space race ahead.

Movie: The Mandalorian and Grogu

While have waited long enough for a new season of The Mandalorian, it appears we will need to settle for a movie instead. The Mandalorian and Grogu will premiere in theaters on May 22, 2026.

The movie trailer dropped earlier this week. It is everything you might expect, but it almost has an Andor feel to it. Add to that the scene of a destroyed All Terrain Armored Transport, and you have everything you need to tie this into the best of Star Wars.

Here is the plot from Disney+:

The evil Empire has fallen, and Imperial warlords remain scattered throughout the galaxy. As the fledgling New Republic works to protect everything the Rebellion fought for, they have enlisted the help of legendary Mandalorian bounty hunter Din Djarin (Pedro Pascal) and his young apprentice Grogu.

That’s not too deep, which is perfect. We do not need trade wars and such – that is too close to the newspaper stories today. We need something fun in a galaxy far, far away.

And maybe, just maybe, this new film can re-energize the Star Wars films again. Cute and simple is probably the recipe for films over the next few years, if only to give everyone a safe harbor from reality.

Space Quote: Three Missions Launched to Monitor the Sun

“These three unique missions will help us get to know our Sun and its effects on Earth better than ever before…This knowledge is critical because the Sun’s activity directly impacts our daily lives, from power grids to GPS. These missions will help us ensure the safety and resilience of our interconnected world.”

–Statement by Joe Westlake, Heliophysics Division director at NASA Headquarters, regarding Wednesday’s launch of three missions to investigate the Sun’s influence across the solar system – NASA’s Interstellar Mapping and Acceleration Probe (IMAP), Carruthers Geocorona Observatory, and the National Oceanic and Atmospheric Administration’s Space Weather Follow On-Lagrange 1 (SWFO-L1) missions.

Pic of the Week: The Indescribable NGC 2775

This week’s image is from the NASA/European Space Agency (ESA) Hubble Space Telescope. It shows the odd galaxy NGC 2275 that is hard to describe. Is it an elliptical galaxy, a spiral galaxy, or something else?

The ESA weighs in on the issue below:

NGC 2775 sports a smooth, featureless centre that is devoid of gas, resembling an elliptical galaxy. It also has a dusty ring with patchy star clusters, like a spiral galaxy. Which is it, then: spiral or elliptical — or neither?

Because we can only view NGC 2775 from one angle, it’s difficult to say for sure. Some researchers have classified NGC 2775 as a spiral galaxy because of its feathery ring of stars and dust, while others have classified it as a lenticular galaxy. Lenticular galaxies have features common to both spiral and elliptical galaxies.

It’s not yet known exactly how lenticular galaxies come to be, and they might form in a variety of ways. Lenticular galaxies might be spiral galaxies that have merged with other galaxies, or that have mostly run out of star-forming gas and lost their prominent spiral arms. They also might have started out more similar to elliptical galaxies, then collected gas into a disk around them.

Some evidence suggests that NGC 2775 has merged with other galaxies in the past. Invisible in this Hubble image, NGC 2775 has a tail of hydrogen gas that stretches almost 100 000 light-years around the galaxy. This faint tail could be the remnant of one or more galaxies that wandered too close to NGC 2775 before being stretched apart and absorbed. If NGC 2775 merged with other galaxies in the past, it could explain the galaxy’s strange appearance today.

A Day in Astronomy: Luna 16 Lunar Sample Return

On this day in 1970, the USSR’s Luna 16 spacecraft returned to Earth with a lunar sample. The Luna 16 spacecraft landed on the Moon on September 20 to collect a 3.5 ounce sample before returning to Earth.

While the Apollo 11 and 12 missions had already returned with more than 120 pounds of lunar material, it was still an important milestone for the USSR’s space program. Two more Luna missions would bring back additional lunar samples in the 1970s.

The Russian’s last attempt to send a spacecraft to study the Moon’s surface was in 2023 with Luna 25, which ended in failure.
