VIPER Hits the SLOPEs
Write a comment
Before NASA's next lunar rover paves the way for long-term human exploration of the Moon, it must first pass a series of rigorous mobility tests along the banks of Lake Erie.
The Simulated Lunar Operations Laboratory, or SLOPE Lab, at NASA's Glenn Research Center in Cleveland is home to multiple sandboxes that mimic the lunar and Martian terrain to evaluate the traction performance and lim NASA's OSIRIS-REx Spacecraft Heads for Earth with Asteroid Sample

After nearly five years in space, NASA's Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx) spacecraft is on its way back to Earth with an abundance of rocks and dust from the near-Earth asteroid Bennu.
On Monday, May 10, at 4:23 p.m. EDT the spacecraft fired its main engines full throttle for seven minutes - its most significant maneuver si In the emptiness of space, Voyager I detects plasma 'hum'

Voyager 1 - one of two sibling NASA spacecraft launched 44 years ago and now the most distant human-made object in space - still works and zooms toward infinity.
The craft has long since zipped past the edge of the solar system through the heliopause - the solar system's border with interstellar space - into the interstellar medium. Now, its instruments have detected the constant drone of Want to become a space tourist

Billionaire Jeff Bezos's space launch company Blue Origin has announced it will sell its first flights into microgravity to the highest bidder.
Blue Origin and its two greatest competitors in the "space tourism" field, SpaceX and Virgin Galactic, claim to be advancing humanity through the "democratisation" of space. But these joyrides aren't opening up access to space for all.
At fac NASA, Axiom Agree to First Private Astronaut Mission on Space Station

NASA and Axiom Space have signed an order for the first private astronaut mission to the International Space Station to take place no earlier than January 2022.
"We are excited to see more people have access to spaceflight through this first private astronaut mission to the space station," said Kathy Lueders, associate administrator for human exploration and operations at NASA Headquarters Flying at up to Mach 16 could become reality with UCF's developing propulsion system

University of Central Florida researchers are building on their technology that could pave the way for hypersonic flight, such as travel from New York to Los Angeles in under 30 minutes.
In their latest research published in the journal Proceedings of the National Academy of Sciences, the researchers discovered a way to stabilize the detonation needed for hypersonic propulsion by creating We could detect extraterrestrial satellite megaconstellations within a few hundred light-years

Starlink is one of the most ambitious space missions we've ever undertaken. The current plan is to put 12,000 communication satellites in low-Earth orbit, with the possibility of another 30,000 later. Just getting them into orbit is a huge engineering challenge, and with so many chunks of metal in orbit, some folks worry it could lead to a cascade of collisions that makes it impossible for satellites to survive. But suppose we solve these problems and Starlink is successful. What's the next step? What if we take it further, creating a mega-constellation of satellites and space stations? What if an alien civilization has already created such a mega-constellation around their world? Could we see it from Earth?
This is the idea behind a recent article posted on the arXiv. It's based on an idea about how civilizations might grow over time, known as the Kardashev scale. It's based on the level of energy a civilization can tap into; Type I uses energy on a global scale, type II a star's worth of energy, and so on.

From iron rain on exoplanets to lightning on Jupiter: 4 examples of alien weather
Write a comment
When Oscar Wilde said "conversation about the weather is the last refuge of the unimaginative" he was unaware of some of the more extreme weather on planets and moons other than Earth.
Since the discovery of the first exoplanet in 1992, more than 4,000 planets have been discovered orbiting stars other than our own.
The continuing research with exoplanets involves trying to identify their atmospheric composition, specifically to answer the question of whether life could exist there. In this search for life though, astronomers have found a huge variety of potential worlds out there.
Here are four examples of bizarre weather on other astronomical bodies—to show how varied an exoplanet atmosphere could be.
1. Iron rain on WASP-76b
WASP-76 is a large, hot exoplanet discovered in 2013. The surface of this monster planet—roughly twice the size of Jupiter—is about 2,200℃ (4,000℉). This means a lot of material that would be solid on Earth melts and vaporizes on WASP-76b.
As described in a particularly famous 2020 study, these materials include iron.
A new era of spaceflight? Promising advances in rocket propulsion
Write a comment
The US Defense Advanced Research Projects Agency (Darpa) has recently commissioned three private companies, Blue Origin, Lockheed Martin and General Atomics, to develop nuclear fission thermal rockets for use in lunar orbit.
Such a development, if flown, could usher in a new era of spaceflight. That said, it is only one of several exciting avenues in rocket propulsion. Here are some others.
Chemical rockets
The standard means of propulsion for spacecraft uses chemical rockets. There are two main types: solid fuelled (such as the solid rocket boosters on the Space Shuttle), and liquid fuelled (such as the Saturn V).
In both cases, a chemical reaction is employed to produce a very hot, highly pressurized gas inside a combustion chamber. The engine nozzle provides the only outlet for this gas which consequently expands out of it, providing thrust.
The chemical reaction requires a fuel, such as liquid hydrogen or powdered aluminum, and an oxidiser (an agent that produces chemical reactions) such as oxygen.
