The year two thousand and twenty is almost upon us. And as always, space agencies and aerospace companies all around the world are preparing to spend the coming year accomplishing a long list of missions and developments. Between NASA, the ESA, China, SpaceX, and others, there are enough plans to impress even the most curmudgeonly of space enthusiasts.Continue reading “Spaceflight Stories Expected for 2020”
NASA has chosen the sampling site for its OSIRIS-REx spacecraft. After narrowing it down to four potential sites and examining them in detail, they’ve settled on one location. Their choice? Nightingale.Continue reading “The Site Has Been Chosen! Here’s Where OSIRIS-REx is Going To Take a Sample from Bennu”
While working at the NASA Johnson Space Center during the 1970s, astrophysicist Donald Kessler predicted that collisions between space debris would become increasingly common as the density of space debris increases in orbit around the Earth – creating a cascading effect. Since 2005, the amount of debris in orbit has followed an exponential growth curve, confirming Kessler’s prediction.
Given that the problem is only going to get worse in the coming years, there is a growing demand for technologies that can remove space debris. Following a competitive process, the ESA recently contracted the Swiss startup ClearSpace Today to create the world’s first debris-removing space mission. This mission, known as ClearSpace-1, is expected to launch by 2025 and will help pave the way for more debris removal missions.Continue reading “An Upcoming ESA Mission is Going to Remove one Piece of Space Junk From Orbit”
NASA’s OSIRIS-REx arrived at asteroid Bennu in December 2018. During the past year, it’s been imaging the surface of the asteroid extensively, looking for a spot to take a sample from. Though the spacecraft has multiple science objectives, and a suite of instruments to meet them, the sample return is the key objective.
Now, NASA has narrowed the choice down to four potential sampling locations on the surface of the asteroid.Continue reading “It’s Time to Decide. Where Should OSIRIS-REx Take a Sample from Bennu?”
Back in November 2018, NASA announced that the Mars 2020 rover would land in the Jezero Crater. Jezero Crater is a geologically diverse area, with an alluvial fan of sediment deposited by an incoming river. That sediment may contain preserved ancient organic molecules, and the deposit is clearly visible in satellite images of the Crater.
But the crater holds something else that has scientists intrigued, something that doesn’t show up so clearly in visible light images: a “bathtub ring” of carbonates, which scientists think could hold fossils.Continue reading “Mars 2020 Rover is Going to a Place on Mars That’s Perfect for Preserving Fossils”
NASA’s New Horizons mission taught us a lot about Pluto, the ice dwarf planet. But the spacecraft sped past Pluto so quickly, we only got high-resolution images of one side of the planet, the so-called “encounter side.” New Horizons gave us a big leap in understanding, but in a way, it asked more questions than it answered.
The next step is clearly an orbiter, and now NASA is starting to seriously consider one.Continue reading “NASA is Now Considering a Pluto Orbiter Mission”
The Moon landings were a huge undertaking. In order to prepare, NASA had to think of every detail, right down to machines for the astronauts to train on. And those machines are an interesting part of space history all on their own.Continue reading “This is the Machine Astronauts Trained on to Land on the Moon”
The X-37B, the US Air Force’s experimental, Orbital Test Vehicle (OTV) has come back down to Earth after 780 days. It landed at the Kennedy Space Center Shuttle Landing Facility on Oct. 27, 2019, at 3:51 a.m. after breaking its own record for time in space. The X-37B has now spent 2,865 total days in orbit.
The question is, what’s it doing up there?Continue reading “X-37B Lands After 780 Days in Orbit Doing ???”
This is sad news. After finding what seemed like a solution to the Mole’s difficulties on Mars, engineers are stymied again. The Mole, or Heat Flow and Physical Properties Package (HP3) has bounced half-way out of its hole.
It’s like Groundhog Day on Mars. If the Mole bounces out of its hole, it means six more weeks of engineers scratching their heads to come up with a solution.Continue reading “InSight’s Heat Probe Has Bounced Back Out Of Its Hole”
