NASA’s InSight Mars Lander (Interior Exploration using Seismic Investigations, Geodesy, and Heat Transport – InSight) was launched on 5 May 2018 at 11:05 UTC aboard an Atlas V-401 rocket. It traveled 483 million kilometers (300 million miles) in almost six months and successfully landed at Elysium Planitia on Mars on 26 November 2018 at 19:52:59 UTC. Shortly after landing, it has sent back the first photo. Now, NASA publishes InSight Mission raw images on its website, you can see them any time you want on the mission’s multimedia webpage.Continue reading InSight Mission Raw Images are available on the web
On January 31, 2014, about 80 minutes after sunset on its 529th Martian day (or sol), NASA’s Curiosity Rover has turned its camera back to home and took this amazing photo of Earth and Moon from a distance of around 99 million miles (160 million kilometers). In the image which has the serial number of PIA17936, Earth can be seen as the brightest point of light in the night sky, a little left of center and our moon is just below Earth.Continue reading Earth, a “Bright Evening Star” as seen from Mars
This size comparison of the Sun and the planets in our solar system is going around frequently, but it’s still amazing to see it. Created by the San Francisco-based artist Roberto Ziche,Continue reading Size comparison of the Sun and the planets
For eons, skywatchers have been fascinated by the pale red dot that not only unpredictably moves backward in the night sky but also shines a compelling blood-red. Its color, indeed, is one of the first features we notice about Mars. It seizes our attention, and its compelling ambiguity has evoked a deep visceral reaction from the nomad in ancient savannas to modern astronomers. The ancient astronomer may be satisfied to know that, in fact, Mars is literally blood-red: the same chemical reaction that occurs in the iron in Mars’ soil is the same is the same chemical reaction that occurs in the hemoglobin molecule. Mars, is, quite literally, blood red. Even with our cutting-edge technology and science, Mars still bewitches and amazes us as seen with these five surprising facts about Mars.Continue reading 5 Surprising Facts about Mars
On August 6, 2012, at 05:17 UTC, NASA has successfully landed a Mini-Cooper-sized rover, Curiosity, on Aeolis Palus in Gale Crater on Mars. The 900-kg rover (899 kg, to be exact, which is 1,982 lbs) is equipped with six 50 cm (20 in) diameter wheels in a rocker-bogie suspension. Notes 1 For the first time in the history of the space exploration, the suspension system also served as landing gear for the vehicle, unlike its smaller predecessors.
Curiosity “soft-landed” (wheels down) on the surface of Mars. But, even it’s called “soft-landing”, the touchdown speed was 0.6739m/s vertical and 0.044m/s horizontal, which could damage the wheels. Plus, while the rover is moving, the wheels should withstand the substantial damage through the rough Martian surface. That’s why the wheels of the Curiosity rover have been one of the biggest technical difficulties encountered on the mission. Notes 2Continue reading How NASA Reinvented The Wheel
All of us remember the iconic opening scene from Wall-E, where the lone robot goes about his daily routine, clearing up rubble. Amid the debris-filled surface of the planet, we see glimpses of how things used to be, before a gross violation of the ecosystem and rampant consumption of energy resources made our planet inhabitable. It is a gloomy picture indeed, and fills us with despair to witness what we are doing to our planet, armed with technological advancements that are gradually eating into the earth’s very soul.
However, the movie also teaches us that it is never too late to turn over a new leaf and mend our ways. Technology, when used to benefit humankind, can actually be the very tool with which we can build our futures, and make our planet a better place for the generations to come. This post is an overview of what could happen in 2050, given the rate of technological progression, with a special emphasis on how we can do good to the planet that has sustained us for so long.Continue reading A Quick Peek Into the Future: 10 Ways Technology Will Transform Our Lives by 2050
Those of us who have grown up watching the iconic space saga Star Wars are quite informed about what robots can accomplish. While that’s only a reel representation, but it definitely points to an abundance of opportunities in the realm of space research.Continue reading The Confluence Of Robotics With Space Research And Exploration
Science has proved itself to be a reliable way to approach all kinds of questions about the physical world. As a scientist, I am led to wonder whether its ability to provide understanding is unlimited. Can it in fact answer all the great questions, the ‘big questions of being’, that occur to us?Continue reading Why it’s only science that can answer all the big questions
To able to reach the space, we need rockets. Rocket engines work by action and reaction (“To every action, there is always opposed an equal reaction” Notes 1) and push rockets forward simply by expelling their exhaust in the opposite direction at high speed and can, therefore, work in the vacuum of space. Space rockets are usually enormous in size, because the bigger the rocket is, the more thrust can produce its engine and can carry more weight into the orbit. Here are the 10 tallest rockets ever launched in the history of space exploration.Continue reading Watch: Top 10 Tallest Rockets Ever Launched
To put things into a perspective, here are the moons of our solar system (including our moon) and their sizes compared to Earth.
