ESA's Hera captures separate views of Didymos and Dimorphos
ಸುದ್ದಿಯಲ್ಲಿ ಏಕೆ?
One asteroid hit by a probe, now seen as two: the DART-Hera planetary defence pair for GS3
Hera resolves the Didymos-Dimorphos pair ahead of its survey.
Why it matters: general awareness

On 18 October 2026 the European Space Agency's Hera spacecraft captured its first clear image showing Didymos and Dimorphos as separate objects, using its black-and-white Asteroid Framing Camera.
Hera is surveying the binary asteroid system whose moon, Dimorphos, was hit by NASA's DART probe in 2022 in a planetary-defence test.

Remember these
- On 18 October 2026 ESA's Hera captured its first clear image showing Didymos and Dimorphos as separate objects
- Image taken with Hera's black-and-white Asteroid Framing Camera
- Dimorphos is the moon of the binary asteroid Didymos
- NASA's DART probe struck Dimorphos in 2022 as a planetary-defence (kinetic impactor) test

How the exam will ask it
ಪ್ರಿಲಿಮ್ಸ್
- Hera is a European Space Agency mission to study the Didymos-Dimorphos binary asteroid system.
- NASA's DART mission tested the kinetic impactor technique by striking Dimorphos, the moon of Didymos, in 2022.
- Lucy is a NASA mission to Jupiter's Trojan asteroids, not a JAXA mission.
ಮೇನ್ಸ್
GS3 (Science and Technology, Space): Asteroid impacts are a low-probability, high-consequence risk, and DART showed that a kinetic impactor can alter an asteroid's orbit. Hera's follow-up survey measures the crater, mass and structure, so the technique can be validated and modelled for real threats. The way forward is international cooperation on detection, shared data and response protocols, with India building its own space situational awareness capacity.

ಈ ಜೋಡಿಗಳನ್ನು ಪರಿಗಣಿಸಿ: ಬಾಹ್ಯಾಕಾಶ ಮಿಷನ್ — ಸಂಸ್ಥೆ
- ಹೆರಾ — ಯುರೋಪಿಯನ್ ಬಾಹ್ಯಾಕಾಶ ಸಂಸ್ಥೆ
- ಡಾರ್ಟ್ — ನಾಸಾ
- ಲೂಸಿ — ಜಾಕ್ಸಾ ಮೇಲಿನ ಎಷ್ಟು ಜೋಡಿಗಳು ಸರಿಯಾಗಿ ಹೊಂದಿಕೆಯಾಗಿವೆ?
- ಒಂದು ಮಾತ್ರ
- ಎರಡು ಮಾತ್ರ
- ಮೂರೂ
- ಯಾವುದೂ ಇಲ್ಲ
ಉತ್ತರ ನೋಡಿ
ಉತ್ತರ: B — ಸರಿಯಾದ ಉತ್ತರ: ಎರಡು ಮಾತ್ರ — ಹೆರಾ ESAದು, ಡಾರ್ಟ್ ನಾಸಾದು; ಲೂಸಿ ನಾಸಾದ ಮಿಷನ್, ಜಾಕ್ಸಾದ್ದಲ್ಲ.
