Hello and welcome. Asteria is an application that utilizes NASA's Mars Rover API to bring you visually stunning images of the Red Planet. With Asteria, you may select any day from the Mars rover's mission timeline and we will populate an image library of photos taken on that day. Mars has captured the minds of individuals for decades, so whether you are a space enthusiast, a student or researcher, Asteria is the perfect tool to learn more about the surface of Mars and its vastly unique geological features, and we are very excited for you to witness them with us.

The purpose of Asteria is to provide an immersive and interactive experience for anyone interested in the exploration of Mars. Our webpage offers a unique perspective on the Red Planet and its environment, allowing you to see the planet through the eyes of NASA's Mars rovers. With its user-friendly interface and easy-to-use functionality, Asteria is the ideal resource for anyone who wants to explore the mysteries of the Red Planet. So come and join us on a journey of discovery as we explore the wonders of Mars with Asteria.

Martian Landscape

Much like Earth, the landscape of Mars is characterized by a variety of features that have been shaped by geological processes over billions of years. Some of the most prominent features on Mars include impact craters (Mars holds 21% of the solar systems impact craters, second only to our moon at 31%), volcanoes such as Olympus Mons which is approximately 3x larger than Mount Everest and is visible from Earth's surface through a high-power telescopic lens. Other interesting landscape features including canyons, such as the Mariner Valley Canyon which is nearly 2,600 miles long and 4x larger than the Grand Canyon, and vast plains spanning up to 3,400 km (2100~ mi) wide also run across the Red Planet.

Mission Activity

NASA's Jet Propulsion Laboratory (JPL) is a federally-funded research and development center located in Pasadena, California. JPL is primarily responsible for the development and operation of robotic spacecraft for many of NASA's space exploration missions, including those of which have the fruits of their labor on display here. JPL's primary mission is to conduct space exploration and Earth science research, and to design, build, and operate robotic spacecraft and planetary rovers. JPL has been responsible for many of NASA's most successful missions, including the Mars Exploration Rovers you see below, the Mars Reconnaissance Orbiter, the Cassini-Huygens mission to Saturn, and the Voyager missions to the outer planets. In addition to designing and building spacecraft, JPL also conducts research on a variety of scientific topics, such as astrophysics, Earth science, and climate change. JPL is home to a number of specialized facilities, including a Deep Space Network for communicating with spacecraft, a Mars Yard for testing rovers, and a Clean Room for assembling and testing spacecraft components Needless to say, JPL plays a critical role in NASA's efforts to explore our solar system and to understand its vast environments.

Perseverance

Launch Date: July 30, 2020

Specifications:

Weight: 2,260 lbs
Top Speed: 0.09 mph
Toolkit: 7 science instruments

About:

Perseverance Landed in Jezero Crater on February 18, 2021; its mission was to help answer the question about signs of past microbial life on the Red Planet. It had a similar objective to Curiosity, it explored rocks, dirt, and air. It's the size of a small SUV. This rover looks for direct signs of past life on Mars. In addition, the Perseverance goal is to test the air in Mars's atmosphere and help Nasa discover methods of getting oxygen from the air in the Martian atmosphere. This would increase Nasa chances of designing items that would allow astronauts to explore Mars in the future.

Spirit and Opportunity

Launch Date: July 7, 2003

Specifications:

Weight: 408 lbs
Top Speed: 0.01 mph
Toolkit: 5 science instruments each

About:

According to NASA Spirit and Opportunity were twin rovers sent to planet Mars to determine whether water ever existed on the Red Planet. The Rovers landed on opposite regions of Mars; Spirit landed in a region called Gusev Crater and found evidence that water may have been once present on the planet millions of years ago. On the other hand, The Opportunity landed on Meridiani Planum. It studied layers of minerals in the rocks, and the evidence it collected suggested there may have been the presence of a salty sea on Mars.

Curiosity

Launch Date: Nov. 26, 2011

Specifications:

Weight: 1,982 lb lbs
Top Speed: 0.09 mph
Toolkit: 10 science instruments

About:

Per NASA Curiosity was sent to Mars to determine if that planet had conditions to support microbial life. This rover is known to be the largest robot to ever land on another planet, it's the size of an SUV. Its big wheels help it roll over rocks and sand without the threat of being stuck. Curiosity landed in Gale Crater which also has a tall mountain in the middle of its existence. This mountain had many layers of rock and each layer had different minerals from a different time period which tells NASA about the possibility that the Red Planet had water at one point.

Countdown to Launch

There are a many variables to consider before NASA's billion dollar tool can be safely launched on it's journey to Mars, and a lot of that relies on the weather. More information on specific launch criteria can be viewed here. In the list below we will display today's weather forecast at the Cape Canaveral Air Force Base where the rovers are launched from so that we can see just how difficult it can be to achieve a successful take off. If any of these criteria fail the all-systems-go ready check, then any launches scheduled for the day would be postponed. However, if all of the weather checks come back green, then the mission would proceed as planned.

Today's Launch Criteria

  • Minimum viable temperature to begin fueling: 44.6 °F
  • Maximum viable temperature to begin fueling: 99.8 °F
  • Maximum affordable humidity percentage for proper visibility: 66.5%
  • Maximum acceptable wind speeds before non-viable turbulence levels occur: 48 MPH
