Last week we talked about sample return missions from the Moon and Mars, but scientists have retrieved samples from other objects in the Solar System, including comets and asteroids. What does it take to return a piece of rock from space, and what have we learned so far?
We’re so familiar with NASA’s exploration efforts in space, but you might be surprised to learn that China launches almost as many rockets as the US. They’ve got their own space exploration program that could soon bring humans to the surface of the Moon. Let’s give a brief overview of China’s space exploration plans.
NASA’s Juno spacecraft has completed dozens of flybys of Jupiter, seeing the planet from many angles and delivering some of the most beautiful images we’ve ever seen of the Jovian world. Now it’s focusing in on Io, sending home images of the tiny volcanic world from just 1,500 km away. And the best is yet to come.
With Artemis 1 completing its robotic flight around the Moon, we know that the SLS works. Next comes Artemis 2, with a crew of astronauts flying past the Moon. If that’s successful, we could see humans set foot on the Moon in December 2025. But there is a long list of challenges to consider that could delay things considerably. Go or no go for launch?
Last week we looked back at some of the ideas that science has changed its mind about. This, we look forward, into the future, at some of the big ideas that astronomers are making progress in. What space science are we looking forward to?
How the time flies. It’s been over a year since JWST went operational, with other missions joining the fun. What new insights have we gained about the Universe thanks to these powerful new tools?
Finally, we reach the end of our tour through the missions in the Solar System. Out beyond Mars, to Jupiter the Kuiper Belt and Beyond. Recorded live during the CosmoQuestX 2023 Hangout-a-Thon.
Another week, another review of space missions in the Solar System. Today we set our sights on the red planet. What are all the active missions at Mars today?
Our journey through missions continues, this time we focus on the Moon. There are many nations on the Moon, near the Moon, around the Moon, travelling to the Moon. It’s a lot. We’ll talk about it today.
It’s time for another series. This time we’re going to look at the missions that are currently in place across the Solar System. Today we’ll start with the key missions here on Earth, studying the planet from above and looking out into the Universe.
Jupiter’s Great Red Spot is one of its most iconic features, first seen hundreds of years ago. Although it’s certainly long-lasting, it’s been changing in size over the last few decades, shrinking and changing in color. Is it fading away? And what can the changes tell us about storms on giant planets?
We’ve looked at Earth’s changing climate, now let’s see what it’s like for another world: Mars. Much looks familiar, but some of it is totally alien, from ice caps of frozen carbon dioxide to planetary dust storms that can obscure the entire world from view.
We’re going back to the Moon. In the next few years humans will set foot on the Moon again, ideally this time to stay. But this will be different than the Apollo era, going to the scientifically fascinating, and difficult southern pole of the Moon. What needs to be done to prepare the way back to the Moon?
The permanently shadowed craters on the Moon are the focus of so much research. That’s because they seem to contain vast reserves of water ice. Water we could use for oxygen, propellant and so much more, but also, to help us understand where the Earth’s water came from.
Launching satellites from Earth is counter-productive. You’ve got to make a satellite that can handle Earth gravity, then the brutal flight to space, then deployment in orbit. What if you could build your spacecraft in space?
The asteroid apocalypse is one of those existential crises that keep astronomers up at night. But the DART mission showed us that we can push an asteroid off its trajectory if we have enough warning. Today we’ll talk about how humanity is building early warning systems to give us time to respond to a dangerous asteroid.
We’ve talked about the rising problem of space junk. Okay, we know it’s an issue. So what can be done about it? Today we’ll talk about ideas to remove space junk, making sure space is open to use for the centuries to come.
Last week we talked about the laws that govern space exploration. This week the rubber hits the road. What are the consequences for actually breaking these rules? Are they really going to stop anyone?
The Universe was inaccessible for most of human history, but the first tentative steps to space in the 20th century made humanity realize that science fiction was becoming science reality. New rules would have to be written to govern how we used this limitless expanse. Today we’ll talk about the Outer Space Treaty of 1967.
Astronomers came together in January to present their newest research, and not surprisingly, the Winter AAS meeting was heavy on news from JWST. What were some of the new results that were announced?
Last week we talked about the missions we’re saying goodbye to. This week, we’re going to talk about some upcoming missions to say hello to. Some are brand new ideas, others are, uh, recycled.
It’s always sad to say goodbye, but when we send our robotic emissaries out into the cosmos, it’s just a matter of time before they shut down. Today we’re going to say goodbye to a few missions which have reached the end of their lives. But they were very good robots.
We’re recording this episode on Halloween, so how could we resist but take advantage of this opportunity. Space is already terrifying enough, you know, with the vast endless emptiness, incomprehensible mysteries, and uncaring coldness. But here are some scary stories to spook it up a notch.
This week we saw the incredible image of DART smashing into asteroid Dimorphos. Beyond avenging the dinosaurs, what can we learn scientifically from this and other asteroid/comet impact missions?
It’s been about 65 years since the Soviets launched the first orbital satellite into low Earth orbit: Sputnik 1. Now there are thousands of satellites in orbit, with tens of thousands on the way. Let’s look at the impact that Sputnik had on the history of spaceflight.
