Comet Whipple-Fedtke-Tevzadze 1942g’s Perihelion: 1943 February 6.72, q = 1.354 AU  The name of Fred Whipple is legendary in cometary astronomy. He spent several decades as an astronomer and professor at Harvard University, and is best known for developing what he called the “icy conglomerate” model of a comet’s nucleus (more commonly referred to as the …

Few, if any, sights in the nighttime sky are more impressive than that of a bright, long-tailed comet. It is little wonder that our ancestors of just a few centuries ago, who had little idea of what they were actually seeing, were amazed and perhaps even terrified of the sight, and even today the appearance …

Educational Resources

Ice and Stone 2020 is a new weekly series of educational material focusing on some of the small bodies of the solar system – comets and asteroids. The Earthrise Institute, a non-profit educational organization founded by Comet Hale-Bopp co-discoverer Alan Hale, is partnering with RocketSTEM and the La Cumbres Observatory to release the material for FREE online …

The United States and Canada are joining forces to encourage a new generation of astronauts. The two countries have cooperated on space exploration since soon after NASA, the U.S. space agency, was founded in 1958. Canada sends astronauts on NASA space missions, and it supplies technology for the International Space Station, among other space efforts. …

Objective Apply trigonometric ratios to the NASA Mars Helicopter Scout so that flight data such as climb angle and average speed can be calculated given initial flight parameters. Vocabulary • Slope: The angle the rille wall makes to the horizontal. • Above Ground Level (AGL): The altitude as measured from the local area. • Altitude: …

All across America and throughout the world, celebrations are being held this month to mark the 50th anniversary of Apollo 11’s first landing on the Moon. Well-traveled author Jerome Pohlen was just a kid when the Saturn V rockets were launching astronauts to the Moon from 1968 until 1972, but that era still has left …

With the 50th anniversary of the Apollo 11 mission to the Moon rapidly approaching, there has been a plethora of books about the Apollo program released during the past year. We’ve been deluged with such books here at RocketSTEM in the past couple of months. That has been a good thing too. The ever-rising stack …

Earth and the ISS

NASA is planning a mission to look for life on Jupiter’s moon Europa and has created a rover that will be able to navigate its icy surface from above and below. That’s how BRUIE — the Buoyant Rover for Under-Ice Exploration — was born. A nimble and buoyant robot, BRUIE can traverse sheets of ice …

When NASA scientists assembled telescopes in her home country of Senegal, Binita Yanni knew very little about astronomy and didn’t realize a career in planetary sciences was even a possibility.

Mars

Going where no helicopter has gone before, humanity’s maiden Martian chopper has entered its final testing phase with the goal of proving the rather difficult feat that a heavier-than-air vehicle can fly in the Red Planet’s extremely thin atmosphere.

Around the Solar System

Thanks to the advanced imaging capabilities of NASA’s Hubble Space Telescope in cooperation with other observatories, astronomers were able to identify and explain a rare and beautiful object in the distant sky: an active asteroid that is in the process of coming apart. The image of the asteroid known as 6478 Gault shows two narrow, comet-like tails …

Gazing at the Universe

Until now, everything we’ve known about black holes — celestial objects with intense gravitation — has been from theories and illustrations. Now, thanks to an international collaboration called the Event Horizon Telescope (EHT), a cosmic portrait of a supermassive black hole exists. At the center of the galaxy Messier 87 (M87) in the Virgo constellation, the …

For a planet, this would be like a day at the spa. After years of growing old, a massive planet could, in theory, brighten up with a radiant, youthful glow. Rejuvenated planets, as they are nicknamed, are only hypothetical. But new research from NASA’s Spitzer Space Telescope has identified one such candidate, seemingly looking billions …

Whilst looking closely at a massive elliptical galaxy and its associated galaxy cluster MACS J1149+2223 — whose light took over 5 billion years to reach us — astronomers have spotted a strange and rare sight. The huge mass of the galaxy and the cluster is bending the light from a much more distant supernova behind …
