How Would We Do Surgery in Space?

Any mission to Mars requires deeper planning than missions to the ISS or the Moon. Based purely on the length of the mission, contingencies branch outwards in complex logistical pathways. What if there’s an accident? What if someone’s appendix bursts?

And what if surgery is needed?

That’s So Metal. NASA’s Psyche Mission is Now Under Construction

In August of 2022, NASA will send a robotic spacecraft to the Main Asteroid Belt to explore a truly unique object: a metal asteroid. This object is known as 16 Psyche, is one of the largest asteroids in the Belt, and is composed almost entirely of iron and nickel. The most widely-accepted theory is that it used to be the core of a protoplanet in the Belt that experienced a massive collision that sent its rocky crust and mantle into space.

The spacecraft, also named Psyche, was submitted as part of a call for proposals for NASA’s Discovery Program in 2015 and was selected as the 14th Discovery mission by 2017. Most recently, the spacecraft passed a crucial milestone by moving from the planning and designing phase to the manufacturing phase, where all of the hardware that will allow it to make the journey is being assembled.

Although InSight’s Mole is Completely Buried, it Might be Stuck Again

You’ve gotta hand it to NASA, and to the German Aerospace Center (DLR.) They’ve been struggling for over a year to get the InSight Lander’s Mole working. There’ve been setbacks, then progress, then more setbacks, as they try to get the Mole deep enough to do its job.

Now the Mole is finally buried completely in the Martian surface, but it might still be stuck.

China’s Mars Rover Launches in Late July

In July there’s another launch window to Mars. It looks like China is ready to take advantage of it, by launching their first rover to the planet. It’s called Tianwen-1, meaning “Heavenly Questions”, or “Questions to Heaven.” The complete mission consists of a lander, an orbiter, and a rover.

Rovers Will be Starting to Make Their Own Decisions About Where to Search for Life

We all know how exploration by rover works. The rover is directed to a location and told to take a sample. Then it subjects that sample to analysis and sends home the results. It’s been remarkably effective.

But it’s expensive and time-consuming to send all this data home. Will this way of doing things still work? Or can it be automated?

If You Could See in X-rays, This is What the Universe Would Look Like

X-ray astronomy helps scientists study neutron stars, binary star systems, and supernova remnants, and even helps detect black holes. But even if human eyes had the ability to see X-rays, we couldn’t just look up at the night sky and see these amazing objects since Earth’s atmosphere absorbs and blocks X-rays. So, thank goodness for space telescopes!  And the newest X-ray instrument in space has just produced a breathtaking view of the Universe, and is the deepest X-ray view of the sky we’ve ever seen.

NASA Thinks it’s Time to Return to Neptune With its Trident Mission

Is it time to head back to Neptune and its moon Triton? It might be. After all, we have some unfinished business there.

It’s been 30 years since NASA’s Voyager 2 spacecraft flew past the gas giant and its largest moon, and that flyby posed more questions than it answered. Maybe we’ll get some answers in 2038, when the positions of Jupiter, Neptune, and Triton will be just right for a mission.

Rocks on Bennu are Cracking Because of the Constant Day/Night Cycling

Asteroid Bennu is blanketed by rocks and huge boulders. And now that the OSIRIS-REx spacecraft is taking a close look at those rocks, researchers are able to see something surprising for an airless body: the rocks have tiny cracks and fissures.  

The cause?

Finally! Mars InSight’s Mole is Now Underground

On June 4th NASA reported that the Mole is finally making some headway. But the instrument is not producing any science yet. Image Credit: NASA/DLR/JPL

It looks like the InSight Lander’s Mole instrument is making some progress. After months of perseverance, the team operating the instrument has succeeded in getting the Mole at least some distance into the ground.

That’s a victory in itself, considering all the setbacks there’ve been. But it’s too soon to celebrate: there’s quite a ways to go before the Mole can deliver any science.

OSIRIS-REx Will Collect a Sample from Bennu on October 20th

The date is finally set for OSIRIS-REx’s sampling maneuver. The spacecraft has been at asteroid Bennu since the end of December 2018. During that time, it’s found a few surprises, and mapped the surface in great detail.

Now, we can circle October 20th on our calendars, as the date OSIRIS-Rex will collect its sample.
