This app helps you discover near-Earth objects (NEOs). Filter by their type (asteroid or comet), closest approach time, closest distance, and diameter. For each NEO, the app shows you an Earth-Moon model with the asteroid (or comet) indicated at the proper location. The app also helps you understand the NEO's size by comparing it to a familiar object. The data on NEOs is provided by NASA's Small Body Database (SBDB) and SBDB Close-Approach Data APIs.
Mars LTE
Explore Mars with detailed information about the Perseverance rover's mission. Learn about its search for ancient life, sample collection, and technology testing for future human exploration. Discover the Ingenuity helicopter's groundbreaking flight capabilities.
- Perseverance rover mission details
- Search for ancient microbial life
- Core sample collection and storage
- Technology testing for human exploration
- Ingenuity helicopter flight information

Launch Date : July 30, 2020 Landing Date : Feb. 18, 2021 Location: Jezero Crater, Mars The Mars 2020 Perseverance Rover will search for signs of ancient microbial life, which will advance NASA's quest to explore the past habitability of Mars. The rover has a drill to collect core samples of Martian rock and soil, then store them in sealed tubes for pickup by a future mission that would ferry them back to Earth for detailed analysis. Perseverance will also test technologies to help pave the way for future human exploration of Mars. Strapped to the rover's belly for the journey to Mars is a technology demonstration — the Mars Helicopter, Ingenuity, may achieve a "Wright Brothers moment “ by testing the first powered flight on the Red Planet.

Verdict
The clearest difference is rating: Mars LTE at 5.0 against NEOscan's 2.7. NEOscan's advantage is update cadence (every 12 months vs every 43 months) and ratings volume (7 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
