Helios B

Helios-A and Helios-B (also known as Helios 1 and Helios 2), are a pair of probes launched into heliocentric orbit for the purpose of studying solar processes. A joint venture of the Federal Republic of Germany (West Germany) and NASA, the probes were launched from the John F. Kennedy Space Center at Cape Canaveral, Florida, on Dec. 10, 1974, and Jan. 15, 1976, respectively.

The probes are notable for having set a maximum speed record among spacecraft at 252,792 km/h (157,078 mi/h or 43.63 mi/s or 70.22 km/s or 0.000234c). Helios 2 flew three million kilometers closer to the Sun than Helios 1, achieving perihelion on 17 April 1976 at a record distance of 0.29 AU (or 43.432 million kilometers), slightly inside the orbit of Mercury. Helios 2 was sent into orbit 13 months after the launch of Helios 1. The Helios space probes completed their primary missions by the early 1980s, but they continued to send data up to 1985. The probes are no longer functional but still remain in their elliptical orbit around the Sun

The Sea’s Strangest Square Mile

You’ve heard of Weird Twitter but now there’s Weird Ocean. This square mile of water in the Lembeh Strait has some of the strangest and most unique marine life on the planet.

Includes an appearance by the always delightful cuttlefish. (via @Colossal)

NASA’s 19-Gigapixel Filmstrip of the Earth

With the newest generation of Landsat satellites up and snappin’, in orbit over 400 miles above us, NASA continues a mission over a generation in the making: Observing a beautiful and changing planet from above.

This video features 56 photos stitched together in a continuous 19-gigapixel image that stretches from Russia to South Africa. Dig in to the interactive “Long Swath” at NASA’s Earth Observatory. This image covers almost 1.7 million square kilometers, but it would take over 300 of them to paint a picture of all of Earth’s surface.

Bonus: Combine this with Google’s Earth Engine to gain a perspective on our planet once reseved for time-traveling astronauts.
