International Space Station Is Racing The Clock After Soyuz Failure

October 11, 2018 by Tom Nardi 120 Comments

Today’s failed Soyuz launch thankfully resulted in no casualties, but the fate of the International Space Station (ISS) is now in question.

Just two minutes after liftoff, the crew of the Soyuz MS-10 found themselves in a situation that every astronaut since the beginning of the manned space program has trained for, but very few have ever had to face: a failure during launch. Today the crew of two, Russian Aleksey Ovchinin and American Nick Hague, were forced to make a ballistic re-entry into the Earth’s atmosphere; a wild ride that put them through higher G forces than expected and dropped the vehicle approximately 430 km from the launch site in Baikonur. Both men walked away from the event unharmed, but while the ordeal is over for them, it’s just beginning for the crew of the ISS.

Until a full investigation can be completed by Roscosmos, Russia’s space agency, the Soyuz rocket is grounded. This is standard procedure, as they obviously don’t want to launch another rocket and risk encountering the same issue. But as the Soyuz is currently the only way we have to get humans into space, this means new crew can’t be sent to the ISS until Roscosmos is confident the issue has been identified and resolved.

Soyuz MS-11, which would have brought up three new crew members to relieve those already on the Station, was scheduled for liftoff on December 20th. While not yet officially confirmed, that mission is almost certainly not going to be launching as scheduled. Two months is simply not long enough to conduct an investigation into such a major event when human lives are on the line.

The failure of Soyuz MS-10 has started a domino effect which will deprive the ISS of the five crew members which were scheduled to be aboard by the end of 2018. To make matters worse, the three current crew members must return to Earth before the end of the year as well. NASA and Roscosmos will now need to make an unprecedented decision which could lead to abandoning the International Space Station; the first time it would be left unmanned since the Expedition 1 mission arrived in November 2000.

Soyuz Rocket Emergency Landing, Everyone OK

October 11, 2018 by Elliot Williams 38 Comments

NASA spokesperson [Brandi Dean] summarized it succinctly: “Confirming again that today’s Soyuz MS10 launch did go into ballistic re-entry mode … That means the crew will not be going to the ISS today. Instead they will be taking a sharp landing, coming back to earth”. While nobody likes last-minute changes in plans, we imagine that goes double for astronauts. On the other hand, it’s always good news when we are able to joke about a flight that starts off with a booster separation problem.

Astronauts [Nick Hague] and [Aleksey Ovchinin] were on their way this morning to the International Space Station, but only made it as far as the middle of Kazakhstan. Almost as soon as the problem occurred, the rocket was re-pathed and a rescue team was sent out to meet them. Just an hour and a half after launch, they were on-site and pulled the pair out of the capsule unharmed. Roscosmos has already commissioned a report to look into the event. In short, all of the contingency plans look like they went to plan. We’ll have to wait and see what went wrong.

Watching the video (embedded below) the only obvious sign that anyone got excited is the simultaneous interpreter stumbling a bit when she has to translate [Aleksey] saying “emergency… failure of the booster separation”. Indeed, he reported everything so calmly that the NASA commentator didn’t even catch on for a few seconds. If you want to know what it’s like to remain cool under pressure, have a listen.

Going to space today is still a risky business, but thankfully lacks the danger factor that it once had. For instance, a Soyuz rocket hasn’t had an issue like this since 1975. Apollo 12 was hit by lightning and temporarily lost its navigation computer, but only the truly close call on Apollo 13 was made into a Hollywood Blockbuster. Still, it’s worth pausing a minute or two to think of the people up there floating around. Or maybe even sneak out and catch a glimpse when the ISS flies overhead.

Maker Faire NY: Developing For The Final Frontier

September 28, 2018 by Tom Nardi 6 Comments

The cost of getting a piece of hardware into space is now cheaper than ever, thanks in no small part to the rapid progress that’s been made by commercial launch providers such as SpaceX. In the near future, as more low-cost providers come online, it should get even cheaper. Within a few years, we could be seeing per kilogram costs to low Earth orbit that are 1/10th what they were on the Space Shuttle. To be sure, this is a very exciting time to be in the business of designing and building spacecraft.

But no matter how cheap launches to orbit get, it’ll never be cheaper than simply emailing some source code up to the International Space Station (ISS). With that in mind, there are several programs which offer students the closest thing to booking passage on a Falcon 9: the chance to develop software that can be run aboard the Station. At the 2018 World Maker Faire in New York we got a chance to get up close and personal with functional replicas of the hardware that’s already on orbit, known in space parlance as “ground units”.

On display was a replica of one of the SPHERES free-flying satellites that have been on the ISS since 2006. They are roughly the size of a soccer ball and utilize CO2 thrusters and ultrasonic sensors to move around inside of the Station. Designed by MIT as a way to study spaceflight techniques such as docking and navigation without the expense and risk of using a full scale vehicle, the SPHERES satellites are perhaps the only operational spacecraft to have never been exposed to space itself.

Expansion port for additional hardware.

MIT now runs the annual “Zero Robotics” competition, which tasks middle and high school students with solving a specific challenge using the SPHERES satellites. Competitors run their programs on simulators until the finals, which are conducted using the real hardware on the ISS and live-streamed to schools.

We also saw hardware from “Quest for Space”, which is a company offering curricula for elementary through high school students which include not only the ground units, but training and technical support when and if the school decides to send the code to the matching hardware on the Station. For an additional fee, they will even work with the school to design, launch, and recover a custom hardware experiment.

Their standard hardware is based on off-the-shelf platforms such as Arduino and LEGO Mindstorms EV3, which makes for an easy transition for school’s existing STEM programs. The current hardware in orbit is setup for experiments dealing with heat absorption, humidity, and convection, but “Quest for Space” notes they change out the hardware every two years to provide different experiment opportunities.

Projects such as these, along with previous efforts such as the ArduSat, offer a unique way for the masses to connect with space in ways which would have been unthinkable before the turn of the 21st century. It’s still up for debate if anyone reading Hackaday in 2018 will personally get a chance to slip Earth’s surly bonds, but at least you can rest easy knowing your software bugs can hitch a ride off the planet.

NASA Wants You… To Design Their Robot

August 19, 2018 by Al Williams 9 Comments

No one loves a good competition more than Hackaday. We run enough to keep anyone busy. But if you have a little spare time after designing your one inch PCB, you might check out the competition to develop a robotic arm for NASA’s Astrobee robot.

Some of the challenges are already closed, but there are quite a few still open for a few more months (despite the published closing date of and these look like great projects for a hacker. In particular, the software architecture and command, data, and power system are yet to start.

But don’t let the $25,000 fool you. That’s spread out over a number of awards for the entire series. Each task has an award that ranges from $250 to $5,000. However, you also have to win that award, of course. If you register, however, you do get a sticker that has flown on the space station.

If you haven’t seen Astrobee, it is a flying robot made to assist astronauts and cosmonauts on the International Space Station. The robot is really a floating sensor platform that can do some autonomous tasks but can also act as a telepresence robot for flight controllers. You might enjoy the second video below if you haven’t seen Astrobee, before.

We covered the Astrobee before. If you’d like to visit the space station yourself, it isn’t quite telepresence, but Google can help you out.

Lost In Space: How Materials Degrade In Space

March 12, 2018 by Steven Dufresne 31 Comments

Hackaday readers are well aware of the problems caused by materials left exposed to the environment over time, whether that be oxidized contact pads on circuit boards or plastics made brittle from long exposure to the sun’s UV rays.

Now consider the perils faced by materials on the International Space Station (ISS), launched beginning in 1998 and planned to be used until 2028. That’s a total of 30 years in an environment of unfiltered sunlight, extreme temperatures, micrometeoroids, and even problems caused by oxygen. What about the exposure faced by the newly launched Tesla Roadster, an entirely non-space hardened vehicle on a million-year orbit around the sun? How are the materials which make up the ISS and the Roadster affected by the harsh space environment?

Fortunately, we’ve been doing experiments since the 1970s in Earth orbit which can give us answers. The missions and experiments themselves are as interesting as the results so let’s look at how we put materials into orbit to be tested against the rigors of space.

Salyut: How We Learned To Make Space Stations

February 12, 2018 by Steven Dufresne 61 Comments

When you think about space stations, which ones come to mind first? You might think Skylab, the International Space Station (ISS), or maybe Russia’s Mir. But before any of those took to the heavens, there was Salyut.

Russia’s Salyut 1 was humankind’s first space station. The ensuing Salyut program lasted fifteen years, from 1971 to 1986, and the lessons learned from this remarkable series of experiments are still in use today in the International Space Station (ISS). The program was so successful at a time when the US manned space program was dormant that one could say that the Russians lost the Moon but won the space race.

The Hard-Learned Lessons Of The Columbia Disaster

February 1, 2018 by Tom Nardi 136 Comments

On February 1st, 2003 at eighteen seconds past 9:00 AM Eastern Standard Time, the Space Shuttle Columbia broke up during atmospheric entry over Texas. Still traveling at approximately Mach 18.3, the disintegration of Columbia was complete and nearly instantaneous. According to the official accident investigation, the crew had at most one minute from realizing they were in a desperate situation to complete destruction of the spacecraft. Due to the design of the Space Shuttle, no contingency plan or emergency procedure could have saved the crew at this point in the mission: all seven crew members were lost in this tragedy.

While the Space Shuttle, officially known as the Space Transportation System (STS) would fly again after the Columbia disaster, even the program’s most ardent supporters had to admit fundamental design of the Shuttle was flawed. Steps needed to be taken to ensure no future astronauts would be lost, and ultimately, the decision was made to retire the Shuttle fleet after primary construction of the International Space Station (ISS) was complete. There was simply too much invested in the ISS at this point to cancel the only spacecraft capable of helping to assemble it, so the STS had to continue despite the crushing loss of human life it had already incurred.

Between the loss of Challenger and Columbia, the STS program claimed fourteen lives in its thirty year run. Having only flown 135 missions in that time, the STS is far and away the most deadly spacecraft to ever fly. A grim record that, with any luck, is never to be broken.

The real tragedy was, like Challenger, the loss of Columbia could have been prevented. Ground Control knew that the Shuttle had sustained damage during launch, but no procedures were in place to investigate or repair damage to the spacecraft while in orbit. Changes to the standard Shuttle mission profile gave future crews a chance of survival that the men and women aboard Columbia never had.
