NASA Chooses Falcon Heavy Over SLS to Launch Europa Clipper, Saving About $2 Billion

The bureaucracy of government control is slowly fading away in space exploration, at least in the US.  A series of delays, cost overruns, and imposed requirements have finally started taking its toll on the Space Launch System (SLS), the next generation NASA rocket system.  Now, the space agency has finally conceded a point to the commercial launch...

A Black Hole Emitted a Flare Away From us, but its Intense Gravity Redirected the Blast Back in our Direction

In 1916, Albert Einstein put the finishing touches on his Theory of General Relativity, a journey that began in 1905 with his attempts to reconcile Newton’s own theories of gravitation with the laws of electromagnetism. Once complete, Einstein’s theory provided a unified description of gravity as a geometric property of the cosmos, where massive objects...

Lightweight Carbon Fiber Reinforced Plastic Fuel Tanks Pass a Critical Test, and Could Knock a lot of Weight off a Rocket’s dry Mass

Material science is still the unsung hero of space exploration.  Rockets are flashier, and control systems more precise, but they are useless without materials that withstand the immense temperatures of forces required to get people and things off the planet.  Now a team from MT Aerospace, working on a grant from ESA, has developed a new type of material...

InSight has Mapped out the Interior of Mars, Revealing the Sizes of its Crust, Mantle, and Core

In May of 2018, NASA’s Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport (InSight) landed on the Martian surface. This mission is the first of its kind, as all previous orbiters, landers, and rovers focused on studying the surface and atmosphere of Mars. In contrast, InSight was tasked with characterizing Mars’ interior...

Bad News. Those Underground Lakes on Mars? They’re Probably Just Frozen Clay

If you were planning an ice-fishing trip to the Martian south pole and its sub-surface lakes observed by radar in 2018, don’t pack your parka or ice auger just yet. In a research letter published earlier this month in Geophysical Research Letters by I.B. Smith et al., it seems that the Martian lakes may be nothing more smectite, that is, a kind of clay....

Starliner Will try Again on August 3 After ISS “Emergency”

The planned launch of Boeing’s CST-100 Starliner test flight to the International Space Station (ISS) has been pushed back to Tuesday, August 3 after a mishap involving a newly docked Russian module. Originally, Starliner’s flight was to take place today, July 30, 2021 but NASA and Boeing officials agreed to delay the flight following a “spacecraft...

The Event Horizon Telescope Zooms in on Another Supermassive Black Hole

On April 10th, 2019, the world was treated to the first image of a black hole, courtesy of the Event Horizon Telescope (EHT). Specifically, the image was of the Supermassive Black Hole (SMBH) at the center of the supergiant elliptical galaxy known as M87 (aka. Virgo A). These powerful forces of nature are found at the centers of most massive galaxies,...

Strange Intersecting Sand Dunes on Mars

In our exploration of Mars, we’ve seen some strange but naturally occurring shapes. Polygons – a shape with at least three straight sides and angles, typically with five or more – have been seen in several different Martian landscapes, and scientists say these shapes are of great interest because they often indicate the presence of shallow ice, or that...

Blue Origin Offers a $2 Billion Discount to get Back in the Lunar Lander Game

Blue Origin has been busy lately.  They launched their founder, Jeff Bezos, into space and put a bid in on NASA’s new Lunar Lander project.  While SpaceX won that contract back in April, Blue Origin has continued to fight for their right to supply the space agency with an alternative lander.  And recently, their not-quite-an-astronaut chief had added...

Searching for Dark Matter Inside the Earth

Dark matter remains one of the greatest mysteries in science.  Despite decades of astronomical evidence for its existence, no one has yet been able to find any sign of it closer to home.  There have been dozens of efforts to do so, and one of the most prominent just hit a milestone – the release and analysis of 8 years of data.  The IceCube Neutrino...
