Japan’s Venus Climate Orbiter Akatsuki was launched on May 21, 2010, and started its active mission in 2015 after an initial orbital insertion failure. Since that time, Akatsuki has continuously observed Venus from orbit until issues began to crop up in 2024 when contact was lost in April of that year due to attitude control issues. […]
While many in the industry were at first skeptical of NASA’s goal to put resupply flights to the International Space Station in the hands of commercial operators, the results speak for themselves. Since 2012, the SpaceX Dragon family of spacecraft has been transporting crew and cargo from American soil to the orbiting laboratory, a capability […]
As you might expect, the University of Puerto Rico at Arecibo has a fascination with radio signals from space. While doing research into the legendary “Wow! Signal” detected back in 1977, they realized that the burst was so strong that a small DIY radio telescope would be able to pick it up using modern software-defined […]
Why build a telescope? YOLO, as the kids say. Having decided that, one must decide what type of far-seer one will construct. For his 10″ reflector, [Carl Anderson] once again said “Yolo”— this time not as a slogan, but in reference to a little-known type of reflecting telescope. Telescope or sci-fi laser gun? YOLO, just […]
It’s been just over 48 years since Voyager 1 was launched on September 5, 1977 from Cape Canaveral, originally to study our Solar System’s planets. Voyager 1 would explore Jupiter and Saturn, while its twin Voyager 2 took a slightly different route to ogle other planets. This primary mission for both spacecraft completed in early […]
It’s not martian regolith, bu it’s the closest chemical match available to the dirt in Gale Crater. (Image: Swinburne University) Every school child can tell you these days that Mars is red because it’s rusty. The silicate rock of the martian crust and regolith is very rich in iron oxide. Now Australian researchers at CSIRO […]
The International Space Station has been in orbit around the Earth, at least in some form, since November of 1998 — but not without help. In the vacuum of space, an object in orbit can generally be counted on to remain zipping around more or less forever, but the Station is low enough to experience […]
It’s not every day we hear of a new space propulsion method. Even rarer to hear of one that actually seems halfway practical. Yet that’s what we have in the case of TFINER, a proposal by [James A. Bickford] we found summarized on Centauri Dreams by [Paul Gilster] . TFINER stands for Thin-Film Nuclear Engine […]
As NASA’s Artemis program trundles onwards at the blazing pace of a disused and very rusty crawler-transporter, the next mission on the list is gradually coming into focus. This will be the first crewed mission — a flyby of the Moon following in the footsteps of 1968’s Apollo 8 mission. As part of this effort, […]
Launched in 2004, the Neil Gehrels Swift Observatory – formerly the Swift Gamma-Ray Burst Explorer – has been dutifully studying gamma-ray bursts (GRBs) during its two-year mission, before moving on to a more general space observation role during its ongoing mission. Unfortunately, the observatory is in LEO, at an altitude of around 370 km. The […]
