About this deal

Since the 1960s, humans have sent dozens of spacecraft to study Mars. Early missions were flybys, with spacecraft furiously snapping photos as they zoomed past. Later, probes pulled into orbit around Mars; more recently, landers and rovers have touched down on the surface. Yes - it’s red because of rust- a reddish chemical substance called iron oxide that occurs when metals react with water and air. Tina Seeger: Well, in the ’90s, they came up with names on the fly. And that’s why you got silly names like “Barnacle Bill,”“Indiana Jones.” But now we compile a list of names ahead of time based on different themes. We draw a grid on the map where each square is a different quadrant that represents a different theme. Curiosity has used names from South America, Scotland; Perseverance uses names from national parks around the world. The largest, most advanced rover NASA has sent to another world touched down on Mars Thursday, after a 203-day journey traversing 293 million miles (472 million kilometers). Confirmation of the successful touchdown was announced in mission control at NASA’s Jet Propulsion Laboratory in Southern California at 3:55p.m. EST (12:55p.m. PST). A day on Mars lasts about 24.6 hours, or just a little longer than a day on Earth. Martian days are called sols — short for solar day — and there are 669.6 sols in a Martian year. Mars' axial tilt is also very similar to our planet's, at about 25 degrees (Earth's is 23.4 degrees), meaning Mars experiences seasons much like those on Earth. How many moons does Mars have?

Why we explore Mars—and what decades of missions have revealed

The Red Planet has been a target for investigations over many centuries. No planet has been so heavily explored, other than our own, according to NASA.

Somewhere during Martian evolution, the planet went through a dramatic transformation, and a world that was once rather Earthlike became the dusty, dry husk we see today. The question now is, what happened? Where did those liquids go, and what happened to the Martian atmosphere? All of the robotic activity is, of course, laying the groundwork for sending humans to the next world over. NASA is targeting the 2030s as a reasonable timeframe for setting the first boots on Mars, and is developing a space capsule, Orion, that will be able to ferry humans to the moon and beyond. The possibility that there were once oceans and rivers on Mars is fairly well established. Observations suggest that there could have been water on the surface as recently as 2 billion years ago.

Well, that all depends on finding water. Water is life, and as Dr Meyer told BBC World Service’s, The Forum, with water anything is possible.Ah yes, in your quiz question you asked what Mars was the Roman god of. I guessed b) the Roman God of Fire. Also with an eye on future Red Planet explorations, the Mars Oxygen In-Situ Resource Utilization Experiment ( MOXIE) technology demonstration will attempt to manufacture oxygen out of thin air – the Red Planet’s tenuous and mostly carbon dioxide atmosphere. The rover’s Mars Environmental Dynamics Analyzer ( MEDA) instrument, which has sensors on the mast and chassis, will provide key information about present-day Mars weather, climate, and dust. Over the last century, everything we’ve learned about Mars suggests that the planet was once quite capable of hosting ecosystems—and that it might still be an incubator for microbial life today.

Mars has been in the news a lot recently with three separate missions being sent to explore the planet’s surface in 2021. Neil and Sam discuss our fascination with the 'Red Planet' and teach you related vocabulary. This week's question Unlike ancient civilisations, modern astronomers have sent satellites to land on Mars and explore its surface. And although no human has set foot on the Red Planet so far, we know a lot about conditions there.

It's always a balancing game to give the supporting characters enough time to tell their stories without taking away from the central story. If you give them too much time, the audience forgets what the real story is and wants to know more about the secondary characters. But if you do it just right, the characters come to life and the reader thinks you told them much more than you actually did. I don't know which I achieved in Red's Planet, but I'm hoping the latter. Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons, and weather. It has a very thin atmosphere made of carbon dioxide, nitrogen, and argon.
