Musk hopes "Mechazilla" will catch and assemble the Starship and Super Heavy boosters for rapid reuse
Friday, 20 August 2021 10:25In January of 2021, Elon Musk announced SpaceX's latest plan to increase the number of flights they can mount by drastically reducing turnaround time. The key to this was a new launch tower that would "catch" first stage boosters after they return to Earth. This would forego the need to install landing legs on future Super Heavy boosters and potentially future Starship returning to Earth.
Musk shared this idea in response to a tweet made by an animator who goes by the Twitter handle Erc X, who asked if his latest render (of a Starship landing next to its launch tower) was accurate. As usual, Musk responded via Twitter, saying:
"We're going to try to catch the Super Heavy Booster with the launch tower arm, using the grid fins to take the load… Saves mass & cost of legs & enables immediate repositioning of booster on to launch mount—ready to refly in under an hour."

The ground crews at SpaceX's South Texas Launch Facility near Boca Chica recently finished stacking the nine sections of bolted steel that make up the tower, which now stands about 145 m (440 ft) tall.

Friday, 20 August 2021 08:30However, this nameless space visitor is not recorded in any known historical account. So how do astronomers know that there was such an interplanetary intruder? Enter comet ATLAS (C/2019 Y4), which first appeared near the beginning of 2020. Comet ATLAS, first detected by the Asteroid Terrestrial-impact Last Alert System (ATLAS), operated by the University of Hawaii, quickly met an untimely
SpaceX 23rd resupply mission will carry bone and plants studies to ISS
Friday, 20 August 2021 08:30The 23rd SpaceX cargo resupply services mission carrying scientific research and technology demonstrations to the International Space Station is targeted to launch in late August from NASA's Kennedy Space Center in Florida. Experiments aboard include an investigation into protecting bone health with botanical byproducts, testing a way to monitor crew eye health, demonstrating improved dext
A 'True' Blue Moon occurs this weekend
Friday, 20 August 2021 08:30The full Moon of Sunday, August 22nd, will be a "Blue Moon" according to the original - but not the most popular - definition of the phrase. In modern usage, "Blue Moon" has come to refer to the second full Moon in a month (the last of these occurred on October 31, 2020) - but that hasn't always been the case. This colorful term is actually a calendrical goof that worked its way into the p
Kleos builds its military knowledge under US DOD program
Friday, 20 August 2021 08:30Kleos Space S.A, a space-powered Radio Frequency Reconnaissance data-as-a- service (DaaS) company, has appointed Lieutenant Colonel (LTC) Mario E. Zaltzman as a military advisor for a 12-week period under a secondment program with the US Department of Defence. LTC Mario Zaltzman is a member of the US Army Reserve, where he is responsible for critical technology and product acquisitio
Russia's Soyuz Spacecraft Launches 34 New OneWeb Satellites Into Orbit
Friday, 20 August 2021 08:30Initially, the launch was scheduled for August 5, but due to satellite production problems, it was reportedly postponed, as some devices had to be replaced because of low-quality components at the company's factory in Florida. Russian space agency Roscosmos will launch a Soyuz 2.1b spaceship with a new batch of 34 UK OneWeb satellites from Baikonur Cosmodrome in Kazakhstan on Friday night.
Vibration tests for Moon rocket help ensure safe travels on road to space
Friday, 20 August 2021 08:30Driving down a bumpy gravel road, even an off-road vehicle experiences bumps and vibrations, partly because of the car's natural frequency. An object's natural frequency is the frequency or rate that it vibrates naturally when struck. When forces like speed and the smoothness of the road are just right, the car will vibrate in tune with that same frequency. Rockets flying through the atmos
NASA spacewalk briefing to highlight new solar array installation
Friday, 20 August 2021 08:30Two astronauts will venture outside the International Space Station Tuesday, Aug. 24, for a spacewalk to install a support bracket in preparation for future installation of the orbiting laboratory's third new solar array. NASA will discuss the upcoming spacewalk during a news conference at 2 p.m. EDT Monday, Aug. 23. Live coverage of the news conference and spacewalk will air on NASA Telev
Construction begins on NOIRLab Windows on the Universe Center
Friday, 20 August 2021 08:30What was once the largest solar observatory in the world is now undergoing a transformation to become a one-of-a-kind facility for sharing the wonders of astronomy with people around the globe. Construction work has started to recast the McMath-Pierce Solar Telescope facility at Kitt Peak National Observatory into the NOIRLab Windows on the Universe Center for Astronomy Outreach. Dedicated
Researchers from IRSOL and IAC solve twenty-year-old paradox in solar physics
Friday, 20 August 2021 08:30In 1998, the journal Nature published a seminal letter concluding that a mysterious signal, which had been recently discovered analysing the polarization of sunlight, implies that the solar chromosphere (a very important layer of the solar atmosphere) is practically unmagnetised, in sharp contradiction with common wisdom. This paradox motivated laboratory experiments and theoretical investigatio
Scientists detect never-before-seen radio waves from nearby stars and distant galaxies
Friday, 20 August 2021 08:30Scientists have measured thousands of nearby stars and far away galaxies that have never been identified before at radio wavelengths, while studying a galactic body that neighbours our own Milky Way galaxy - the Large Magellanic Cloud. Led by Keele University PhD student Clara M. Pennock and Reader in Astrophysics, Dr Jacco van Loon, the international team of researchers used the Australia
